The CBRS Alliance and the Wireless Innovation Forum announced this week that Ericsson, Nokia and Sercomm have joined Arris’ Ruckus Networks unit as the first technology vendors to achieve certification for new CBRS band devices.

Last month, Ruckus said that it had been given FCC certification for its entire portfolio of “OpenG”-branded access points designed to work in the 3.5 Ghz Citizens Broadband Radio Service (CBRS) spectrum.

Cable and wireless operators are exploring opportunities for the Citizens Broadband Radio Service Device band, a 150 MHz-wide portion of largely underused spectrum existing between 3.55 GHz and 3.7 GHz. CBRS will ultimately be used for private LTE networks such as airports and industrial campuses.

Having the telecom industry’s major vendors certified is a major step in the broader plan to have CBRS commercial deployments achieved by the end of the year. Earlier today, Federated Wireless said that it has asked the FCC for permission to move forward with commercial CBRS deployments as soon as October, the company announced.
